Best ResponseYou've already chosen the best response.0What is the highest point it will reach at the end of the first swing?

Best ResponseYou've already chosen the best response.1In this system, btw, energy is conserved. Hence the bob at the end of the pendulum will stop at the same height, on both sides. If it didn't, and it stopped higher, energy was added; if it stopped lower, energy was lost.

Best ResponseYou've already chosen the best response.0Let the height at which K.E And PE are equal be x. P.E=mgx. Total energy= mgh h=4(Conservation of energy) Therefore, mgx=mgh/2 x=h/2

Best ResponseYou've already chosen the best response.1No, that's not right. It's not that we must necessarily have 1/2 of the PE at the top of its swing.
